Install Drain Joint - Bosch CLIMATE 8000 RAC Installation Manual

SPECIAL CONSIDERATIONS FOR EXTREME WEATHER
If the unit is exposed to heavy wind:
Install unit so that air outlet fan is at a 90° angle to the direction
of the wind. If needed, build a barrier in front of the unit to
protect it from extremely heavy winds.
See Fig. 5.2 and Fig. 5.3 below.
If the unit is frequently exposed to heavy rain or snow:
Build a shelter above the unit it to protect it from the rain or
snow. Be careful not to obstruct air flow around the unit.
Distance must be >500mm.
Step 2: Install drain joint
Heat pump units require a drain joint. Before bolting the
outdoor unit in place, you must install the drain joint at the
bottom of the unit. Note that there are two different types of
drain joints depending on the type of outdoor unit.

If the drain joint comes with a rubber seal (see Fig. 5.4 - A ),
do the following:
1. Fit the rubber seal on the end of the drain joint that will
connect to the outdoor unit.
2. Insert the drain joint into the hole in the base pan of the unit.
3. Rotate the drain joint 90° until it clicks in place facing the
front of the unit.
4. Connect a drain hose extension (not included) to the drain
joint to redirect water from the unit during heating mode.
If the drain joint doesn't come with a rubber seal
(see Fig. 5.4 - B ), do the following:
1. Insert the drain joint into the hole in the base pan of the unit.
The drain joint will click in place.
2. Connect a drain hose extension (not included) to the drain
joint to redirect water from the unit during heating mode.
IN COLD CLIMATES
In cold climates, make sure that the drain hose is as vertical as
possible to ensure swift water drainage. If water drains too
slowly, it can freeze in the hose and flood the unit.
